Heat Treatment
Hardening: High speed gas/circulating atmosphere (Only suitable for small dimensions). Oil (60–80°C/140–175°F). Martempering bath 300°C (570°F) max. 4 minutes, then air.
Tempering: Choose the tempering temperature according to the hardness required by reference to the tempering graph. Temper twice with intermediate cooling to room temperature. Lowest tempering temperature 180°C (360°F) for small inserts, but preferred minimum is 250°C (480°F). Holding time at temperature minimum 2 hours.
Diagram note: The diagram is valid for small samples 15 x 15 x 40 mm (0.6 x 0.6 x 1.6 in.) austenitized 30 min. at 850°C (1560°F), quenched in air and tempered 2 + 2 hours.
